the accompanying Patented Nov. 29, 1932 UNITED STATES PATENT OFFICE RALPH L. LEE, OF DAYTON, OHIO, ASSIGNOR TO DELCO-LIGHT COMPANY, OF DAYTON, OHIO, A CORPORATION OF DELAWARE DOMESTIG APPLIANCE Application filed April 17,

This invention relates to laundry apparatus, and more particularly to ironing machines comprising a motor driven padded roll cooperating with an ironing shoe movable toward or away from the ironing roll.

@ne of the objects of the present invention is to vary the pressure between the ironing roll and the ironing shoe in accordance with the amount of power required to turn the ironing roll. Tn order to accomplish this object, means are provided for using the torque of the motor to supply the pressure between the ironing shoe and the roll.

. Further objects and advantages of the present invention will be apparent from the following description, reference being had to drawing, wherein a preferred embodiment of one form of the present invention is clearly shown.

Tn the drawing:

Fig. 1 is a perspective view of an ironing machine provided with a form of the present invention;

Figs. 2 and 3 are end views thereof partly broken away for the sake of clearness, showing the ironing shoe in normal and operating positions. respectively. 3

Referring to the drawing, the ironing machine includes side frames 20 and 21 connected by tie rods 22 and 23 and by a table 24. The ironing shoe 25, which is heated in any suitable manner, is supported by arms 26 and 27 whichv are journaled upon tie rod 23. The shoe 25 is shaped to conform with the padded ironing roll 28 which is provided with shafts 29 and 30 journaled upon the frames 20 and 21, respectively.

Adjacent the frame 21, the roll 28 is connected with a gear 31 which meshes with a gear 32 connected with a gear 33 which in turn meshes with a gear 34 driven by a motor Motor .35 is attached by screws 36 to a frame 37 which is loosely journaled upon the shaft 30. Frame 37 is provided with arms '38 and 39. Arm 38 is connected by a link 40 with a lever arm 41 pivoted at arm 42 upon the frame 21. The arm 41 is connected with a brake shoe 43 for engaging a friction surface 44 of the roll 28 adjacent one end of its padded surface. A spring 45 normally 1824. Serial No. 707,250.

maintains the shoe 43 in engagement with the brake surface 44.

A link 46 connects the arm 39 with the ironing shoe 25. The motor 35 is reversible and is controlled by controller 50 including a lever 51 movable into three positions designated F, U and R in Fig. 1. When the lever 51 is opposite O, the motor is inoperative or off; when opposite F, the motor will rotate so that the roller 28 will move in the direction of arrow 52 in Fig. 1 or toward the ironing shoe 25; and when the controller handle 51 is opposite -R-, the ironing roller 28 will rotate in the opposite direction.

When the motor is at rest the ironing shoe 25 will be spaced slightly from the roller and the brake 43 will be applied to the brake drum 44. When the motor begins to turn the roller 28 will not revolve immediately, but the torque of the motor will tend to cause the frame 37 to turn in a direction depending on the direction of rotation of the motor, about the shaft 30, as shown in Fig. 3. This motion of the motor tends to draw the ironing shoe 25 toward the roller 28 and release the brake shoe 43. It is apparent that the greater the friction between the ironing shoe and roller the greater will be the pressure between these members on account of the increase in torque of the motor.

The ironing shoe is provided with a projection suitably shaped for ironing rufiies and the like. The article is moved under the pro jection 60 a short distance and then withdrawn by manipulating the controller handle 51 into positions F and R.

While the form of embodiment of the invention as herein disclosed, constitutes a preferred form it is to be understood that other forms might be adopted all coming within the scope of the claims which follow.

What is claimed is as follows:

1. An ironing machine comprising, in combination, an ironing roll member; an ironing shoe member; a motor for driving the roll member; gearing connecting the motor and roll; a frame carrying the motor and pivoted about the axis of one of the gears and supporting another gear for orbital movementabout the first gear and means connecting the frame with the ironing shoe to move the said shoe relative to the ironing roll.

2. An ironing member comprising, in combination, an ironing roll having a shaft provided with a gear; an ironing shoe; a motor; a frame suspended from the roll-shaft and including means at its free end for supporting the motor; gearing carried by the frame for connecting the motor with the gear on the roll-shaft; and means connecting the frame and the ironing shoe to move the latter in response to the reaction of certain of. said gears.

8. An ironing machine comprising, in combination, an ironing roll having a shaft provided with a gear; an ironing shoe; a motor; a frame suspended from the roll-shaft and having provisions at its free end for carrying the motor; gearing mounted on the frame for connecting the motor with the roll-shaft gear; a brake normally holding the roll stationary; and means responsive to the movement of the frame about the roll shaft for releasing the brake and for causing the ironing'shoe to move toward the roll.

4:. An ironing machine comprising, in combination, an ironing roll member; an ironing shoe member; an electric motor for driving the roll; gearing connecting the motor and roll member, said motor being pivotally mounted and adapted to be moved about the pivot in response to torque reaction thereof when driving the roll member; and means connecting one of said members and the motor for causing a relative shifting of the members when the motor moves about the pivot.

5. An ironing machine comprising, in combination, an ironing roll member; an ironing shoe member; an electric motor for driving the roll; gearing connecting the motor and roll member, said motor being pivotally mounted and adapted to be moved about the pivot in response to torque reaction thereof when driving the roll member; and means connecting the shoe member and the motor for causing the shoe member to be shifted relative to the roll member when the motor moves about the pivot.

6. An ironing machine comprising, in combination, an ironing roll member; a brake member therefor; an electric motor for driving the roll member; said motor having at least a part adapted to be shifted in response to torque reaction of the motor when the motor is rendered operative to drive the roll member; and means connecting one of said members and the said motor part, said means also causing a relative shifting of the members upon starting of the motor.

7. An ironing machine comprising, in combination, an ironing roll member; a brake member therefor; an electric motor for driving the roll member; said motor having at least a part adapted to be shifted in response to torque reaction of the motor when the motor is rendered operative to drive the roll member; and means connecting the brake with said motor part for causing the brake to be released from the roll upon starting of the motor.

8. An ironing machine comprising incombination, an ironing roll member, an ironing shoe member, an electric motor for driving the roll member, said motor having at least a part adapted to be shifted in response to torque reaction of the motor, and means for connecting said part and one of said ironing members for transmitting motion of said part to said member.

9. An ironing machine comprising in combination, an ironing roll member, an ironing shoe member, an electric motor for driving the roll member, said motor having at least a part adapted to be shifted in response to torque reaction of the motor, and means for connecting said part and said shoe member for transmitting motion of said part to said member.

10. An ironing machine comprising, in combination, an ironing roll member; an ironing shoe member; a motor; gears transmitting motion from the motor to the roll member for rotating said roll member; and means responsive to the reaction between the roll driving gears when the motor is operating, for urging one of said members towards the other. y

In testimony whereof I hereto affix my signature.
